I have a MAC that can Run both MAC and PC versions of my Software. The two version are subtly different but on one machine. I will work on the PC side and sometimes on apple. I am PC and learning Apple. I assume this is classified as running only one at a time on the Mac and not cause license issues?
The Windows virtual machine under Parallels is no different than a physically separate machine as far as licensing goes. Unless you have more than one license, you should only be able to run Archicad on either the Windows VM or the native Macos.
I still have a Codemeter hardware protection key. I allocate it (USB device assignment) to the Windows VM if I want to run Archicad there... and have to release it back to Macos to launch AC on the Mac.
Note that Parallels provides only very rudimentary graphics performance for Windows VMs, so even though the VM should perform noticeably slower than Archicad native on your Mac... any 3D window work will be even slower.
